⦁ Gravity
Part 1A. Procedure:
⦁ Go to the PhET simulation “Under Pressure” https://phet.colorado.edu/en/simulation/under-pressure
⦁ Push the big Play arrow.
⦁ Start with the default settings.
⦁ Fill the tank with water and select “Ruler” and “Grid.”
⦁ Adjust the ruler to line up with the grid as shown in the image below.
⦁ Click on the pressure gauge and drag it toward the water.
⦁ Using the pressure gauge, measure the pressure in the water at every 0.50 m from the surface (0 meters) to the bottom.
⦁ Record measurements made at each level on the table below.
⦁ Provide a screenshot of your measurement at 1.5 meters*
